Task Scheduler Error 2147943645
Task Scheduler Error Number 2147943645, is reported when user is not logged in, but has a task set up to run under their user name.
This one is a fairly simple one, another of the helpful Microsoft Error codes, discovered when a client asked us to look into why a scheduled task wasn't running until they had logged in and started it manually. Due to client sensitivity I can't post a picture from their server, but have created a dummy one below.
It only requires a simple change to the Security Options where you change the selected radio button from "Run only when user is logged in" to "Run whether user is logged on or not".
Once changed and saved, you will be prompted for your password so that it can run while you are away.
